ตัวแปลงไฟล์ออนไลน์ฟรี AVCHD เป็น NIST

AVCHD is a video codec designed for recording high definition videos in 720p, 1080i and 1080p modes on such rewritable discs as Blu-Ray and AVCHD, hard disks and memory cards. The AVCHD standard implies using of AVC video compression format, AC3 audio codec and MTS or M2TS file extension. The main feature of the codec is high compression efficiency together with high image quality. But here comes the main flaw - the codec is really heavy for playback.

SPHERE (SPeech HEader Resources) is a file format defined by NIST (National Institute of Standards and Technology) and is used with speech audio. SoX can read these files when they contain μ-law and PCM data. It will ignore any header information that says the data is compressed using shorten compression and will treat the data as either μ-law or PCM. This will allow SoX and the command line shorten program to be run together using pipes to encompasses the data and then pass the result to SoX for processing.
